Data Management Applications for the Service Preparation Subsystem

Friday, 04 September 2009

These software applications provide
intuitive User Interfaces (UIs) with a
consistent look and feel for interaction
with, and control of, the Service
Preparation Subsystem (SPS). The elements
of the UIs described here are the
File Manager, Mission Manager, and Log
Monitor applications. All UIs provide
access to add/delete/update data entities
in a complex database schema without
requiring technical expertise on the
part of the end users. These applications
allow for safe, validated, catalogued
input of data. Also, the software has
been designed in multiple, coherent layers
to promote ease of code maintenance
and reuse in addition to reducing
testing and accelerating maturity.

The File Manager provides an interface
for interactively publishing data
input files to a relational SQL-compliant
database. It extracts/captures metadata
automatically for use in building and
maintaining the catalog of available
data. Also, File Manager visualizes the
data catalog in a tree format for easy use.

Mission Manager provides a single
interface to define critical parameters
describing both flight-and ground-based
projects. Log Monitor provides access to
system events recorded in execution of
automatic generation of support data.
This interface is critical in identifying
events requiring attention/intervention
to meet mission requirements.

The applications comprising the SPS
User Interface Portal run on any platform
that supports Java Runtime Environment
1.4.2. The UIs can interact with any suitably
configured, SQL-compliant database,
and the content-driven nature of the UIs
allows them to be easily adapted to present
custom data. These applications are
highly portable, and were designed for
automatic deployment as WebStart applications,
which reduces the effort involved
in installing and updating these programs
across dozens of user workstations at various
physical locations.
